Without a doubt, exercise provides enormous benefits whether you are expecting or not. But, in pregnant women, it is even encouraged because it not only helps the mother, but also the unborn baby. It should be noted though that expectant mothers who have pre-existing medical conditions are not advised to participate in exercises.
The Centers for Disease Control and Prevention (2008 Physical Activity Guidelines) recommends that healthy women should engage in moderate aerobic exercises during and after pregnancy for 2.5 hours spread over the course of a week. Doing so will help improve cardiovascular functioning, reduce stress and lower the risks of preeclampsia and gestational diabetes.
Those who exercise can expect an enhanced mood and improved overall wellbeing throughout pregnancy. Your unborn fetus will also feel the effects of increased oxygen delivery due to exercise reducing the chances of congenital heart diseases and learning disabilities.
The positive effects of exercising during pregnancy are discussed in detail in this article.
